Performance testing Trend in Australia

From last 2 quarters the demand of performance testing has increased in Australia. When the first quarter started the market was dry in terms of job generation after July, markets picked up and reach to its peak stage now. 

As per my opinion if anyone wants to hop then this is a right time. This article will throw some light on what is Performance Testing, why it is necessary and different techniques of performance testing:

 What is Performance testing in software?

Performance testing, a non-functional testing technique performed to determine the system parameters in terms of responsiveness and stability under various workload. Performance testing measures the quality attributes of the system, such as scalability, reliability and resource usage.

• It is a type of non-functional testing.
• Performance testing is testing that is performed, to determine how fast some aspect of a system performs under a particular workload.
• It can serve different purposes like it can demonstrate that the system meets performance criteria.
• It can compare two systems to find which performs better. Or it can measure what part of the system or workload causes the system to perform badly.
• This process can involve quantitative tests done in a lab, such as measuring the response time or the number of MIPS (millions of instructions per second) at which a system functions.

Why to do performance testing:

• Improve user experience on sites and web apps
• Increase revenue generated from websites
• Gather metrics useful for tuning the system
• Identify bottlenecks such as database configuration
• Determine if a new release is ready for production
• Provide reporting to business stakeholders regarding performance against expectations

Performance Testing Techniques:

Load testing -It is the simplest form of testing conducted to understand the behaviour of the system under a specific load. Load testing will result in measuring important business critical transactions and load on the database, application server, etc., are also monitored.

Stress testing -It is performed to find the upper limit capacity of the system and also to determine how the system performs if the current load goes well above the expected maximum.

Soak testing -Soak Testing also known as endurance testing, is performed to determine the system parameters under continuous expected load. During soak tests the parameters such as memory utilization is monitored to detect memory leaks or other performance issues. The main aim is to discover the system's performance under sustained use.

Spike testing -Spike testing is performed by increasing the number of users suddenly by a very large amount and measuring the performance of the system. The main aim is to determine whether the system will be able to sustain the workload.
